2.06s3-beta4 adds many translations and new features such as BTRFS support, Linux from /boot partition, partition labels and support for booting GNU/Hurd and ReactOS.

Super Grub2 Disk 2.06s3-beta4 is here.

Super GRUB2 Disk is a live cd that helps you to boot into most any Operating System (OS) even if you cannot boot into it by normal means.

A new beta release

This new version is packed with many new features. New Hungarian, Traditional Chinese, Polish and Japanese translations. Debian and Ubuntu secureboot binaries have been updated so that they properly work on updated or recent UEFIs. (Fix) Force to update devices after enabling native disk drivers. Added BTRFS support all over Super Grub2 Disk (Thanks to thermon!). Fixed the use of unicode.pf2. grub.cfg files are now searched at EFI partitions. diskpartchainboot.cfg: Fix quoted label. Operating System specific options: EFI, FreeBSD, FreeDOS, Linux, Mac OS X, MSDOS, Windows 98, Windows NT, Windows Vista (and newer). New Operating Systems: GNU/Hurd, ReactOS and Linux from /boot partition. Partition labels. Overall redesign. Refactor unicode font file generation.

Feedback on Arch GNU/Hurd is welcome because the current implementation is based on Debian GNU/Hurd.

Feedback on SecureBoot support is welcome.

I plan to release this same code as an stable release in about a month so please if something worked for you before in a previous Super Grub2 Disk version and it no longer works for you please report.

You can give us feedback in github issues page so that we can fix it properly. Please specify the exact filename you are using.

Please remember that there has been a renaming of Super Grub2 Disk files. So filenames with ‘classic’ on them means that they do NOT support SecureBoot.

Enjoy the beta and, once again, please give us feedback to report us if it works ok or not for you.

We are going to see which are the complete Super Grub2 Disk features with a demo video, where you can download it, the thank you – hall of fame and some thoughts about the Super Grub2 Disk development.

Please do not forget to read our howtos so that you can have step by step guides (how to make a cdrom or an usb, how to boot from it, etc) on how to use Super Grub2 Disk and, if needed, Rescatux.

Tour

Here there is a little video tour in order to discover most of Super Grub2 Disk options. The rest of the options you will have to discover them by yourself.

Features

Most of the features here will let you boot into your Operating Systems. The rest of the options will improve the Super Grub2 Disk operating systems autodetecting (enable RAID, LVM, etc.) or will deal with minor aspects of the user interface (Colours, language, etc.).

• Change the language UI

Bootable ISOs (in /boot-isos or /boot/boot-isos

• Extra GRUB2 functionality
  • Enable GRUB2’s LVM support

• Reboot the computer

Supported Operating Systems

Excluding too custom kernels from university students Super Grub2 Disk can autodetect and boot most every Operating System. Some examples are written here so that Google bots can see it and also to make more confident the final user who searchs his own special (according to him) Operating System.

• Windows
  • Windows 10
  • Windows Vista/7/8/8.1
  • Windows NT/2000/XP
  • Windows 98/ME
  • MS-DOS
  • FreeDOS
• GNU/Linux
  • Direct Kernel with autodetected initrd

• vmlinuz-*
• linux-*
• kernel-genkernel-*

Debian / Ubuntu / Mint

Mageia

Fedora / CentOS / Red Hat Enterprise Linux (RHEL)

openSUSE / SuSE Linux Enterpsise Server (SLES)

Arch

Any many, many, more.

• FreeBSD
  • FreeBSD (single)
  • FreeBSD (verbose)
  • FreeBSD (no ACPI)
  • FreeBSD (safe mode)
  • FreeBSD (Default boot loader)
• EFI files
• Mac OS X/Darwin 32bit or 64bit

Support for different hardware platforms

Before this release we only had the hybrid version aimed at regular pcs. Now with the upcoming new EFI based machines you have the EFI standalone versions among others. What we don’t support is booting when secure boot is enabled.

• Most any PC thanks to hybrid version (i386, x86_64, i386-efi, x86_64-efi) (ISO)
• EFI x86_64 standalone version (EFI)
• EFI i386 standalone version (EFI)
• Additional Floppy, CD and USB in one download (ISO)
  • i386-pc
  • i386-efi
  • x86_64-efi

Known bugs

• Non English translations are not completed

Supported Media

• Compact Disk – Read Only Memory (CD-ROM) / DVD
• Universal Serial Bus (USB) devices
• Floppy (1.98s1 version only)

NOTE:   The hybrid version should work in most any machine you might have. Please download that version. Non scientific machine names Description Oldie x86   These are very old machines that only have 32-bit processors. Their supported architecture for boot is i386. Oldie 64bit   These are old machines, usually from 2010 year or before. They have 64-bit processors. Their supported architectures for boot are: i386 and x86_64. UEFI 64bit   These are new machines, usually from 2011 year or after. They have 64-bit processors. Their supported architecture for boot is: x86_64-efi. If you enable CSM (also known as legacy boot) support on them they also support i386 and x86_64. UEFI 32bit   These are new machines, usually from 2011 year or after. They are very rare. They have either 64-bit processors or 32-bit processors but somehow boot initially in 32-bit mode. Their supported architecture for boot is: i386-efi. I highly doubt you can enable CSM support on these machines. NOTE:   The hybrid version should work in most any machine you might have. Please download that version.

Thank you – Hall of fame

I want to thank in alphabetical order:

• The upstream Grub crew. I’m subscribed to both help-grub and grub-devel and I admire the work you do there.
• Necrosporus for his insistence on making Super Grub2 Disk smaller.

The person who writes this article is adrian15 .

And I cannot forget about thanking bTactic, the enterprise where I work at and that hosts our site.

Some thoughts about Super Grub2 Disk development

Super Grub2 Disk development ideas

I think we won’t improve Super Grub2 Disk too much. We will try to stick to official Grub2 stable releases. Unless a new feature that it’s not included in official Grub2 stable release is needed in order to give additional useful functionalities to Super Grub2 Disk.

I have added some scripts to Super Grub2 Disk build so that writing these pieces of news is more automatic and less prone to errors. Check them out in git repo as you will not find them in 2.02s8 source code.

Old idea: I don’t know when but I plan to readapt some scripts from os-prober. That will let us detect more operating systems. Not sure when though. I mean, it’s not something that worries me because it does not affect too many final users. But, well, it’s something new that I hadn’t thought about.

Again, please send us feedback on what you think it’s missing on Super Grub2 Disk.

Rescatux development

I want to focus on Rescatux development on the next months so that we have an stable release before the end of 2017. Now I need to finish adding UEFI features (most finished), fix the scripts that generate Rescatux source code (difficult) and write much documentation.
